In‐Sensor Passive Speech Classification with Phononic Metamaterials Open
Mitigating the energy requirements of artificial intelligence requires novel physical substrates for computation. Phononic metamaterials have vanishingly low power dissipation and hence are a prime candidate for green, always‐on computers.…

Binary classification of spoken words with passive elastic metastructures. Open
Many electronic devices spend most of their time waiting for a wake-up event: pacemakers waiting for an anomalous heartbeat, security systems on alert to detect an intruder, smartphones listening for the user to say a wake-up phrase. These…

Broadband acoustic invisibility and illusions Open
The active manipulation of sound waves replaces physical with virtual media to create acoustic invisibility and illusions.

Closed-aperture unbounded acoustics experimentation using multidimensional deconvolution Open
In physical acoustic laboratories, wave propagation experiments often suffer from unwanted reflections at the boundaries of the experimental setup. We propose using multidimensional deconvolution (MDD) to post-process recorded experimental…

Real-Time Immersion of Physical Experiments in Virtual Wave-Physics Domains Open
We immerse a two-dimensional physical wave-propagation experiment in a virtual (simulated) environment in real time. This enables broadband hybrid wave experimentation in physical media that may be governed by unknown physics, embedded sea…

Immersive Wave Propagation Experimentation: Physical Implementation and One-Dimensional Acoustic Results Open
We present a fundamentally new approach to laboratory acoustic and seismic wave experimentation that enables full immersion of a physical wave propagation experiment within a virtual numerical environment. Using a recent theory of immersiv…
